00:12 < monteslu> vim plugin? I'm looking for the eclipse plugin and
debugger :)
00:12 < daganev> when you compare it to javascript, you make people think
its a RIA language
00:12 < kingfishr> iant, bingo thanks
00:12 <+iant> Suhail: sure, we're aiming for both, we'll see
00:12 <+agl> monteslu: misc/vim/go.vim
00:12 < Suhail> iant: i guess I am assuming too that development in Go is
not as fast =\
00:13 <+iant> monteslu: no eclipse yet
00:13 < jcgregorio> agl: thanks, let me know if there's patches or tests you
want me to run, since the error seems to not appear consistently across all 9.04s
00:13 < monteslu> daganev, when you compare syntax?

00:14 <+iant> Suhail: thx, two of the creators of Go invented UTF-8

00:22 < Kniht> should I have checked out go into $GOROOT? (or should I set
GOROOT to where I checked it out instead of ~/go?)
00:22 < MarkBao> would it be a good idea to refer to things Go-related as
golang?

user package repository
00:23 < dsal> thiaguetz: I did it wrong initially. It's going for me now.

00:24 < vhold> 6g's default behavior on things that seem like warnings is
interesting.. declaring and not using a variable is fatal
00:24 < vhold> Google's hard line attitude towards wasted variables!
00:24 < sstangl> hm, I wonder why rpike chose names that conflict with the
plan9 C compiler.
00:24 < kuroneko> iant: does it still ignore ABIs? :P
00:24 <+iant> kuroneko: yes
00:24 <+iant> sstangl: they're the same names
00:25 < kuroneko> *sigh*
00:25 < sstangl> iant: I noticed. is anyone working on a plan9 port?

00:29 <+agl> thiaguetz_: you need $GOBIN in your path.

00:34 <+agl> joeyadams: you have a bad value for GOARCH
00:35 <+agl> vhold: party that's a result of all the UTF-8 processing that
you don't see and partly that 6g generates good code, but not great code.
00:35 < thiaguetz> agl: ohhhhhhhhh i got it! i was reading how all.bash
works
00:35 < joeyadams> ah, thanks

00:38 < joeyadams> Is arm a big-endian platform?
00:39 < vhold> agl: is the utf8 aspect only being introduced by bufio? Or
is that happening down at the byte level before stringification ?
00:39 <+agl> joeyadams: typically yes
00:39 < sstangl> opensourcenut: it's true :)
00:39 < kaib> joeyadams: bi-directional but 5g is little endian.
00:39 < sstangl> opensourcenut: I'm writing a driver for it now, actually.
00:39 -!- thiaguetz [n=thiaguet@189.96.212.96] has quit ["[]'s"]
00:39 < joeyadams> So go hasn't been tested on big endian, then?
00:39 <+iant> vhold: the source code is UTF-8
00:39 < opensourcenut> sstangl: Plan9 is quite a difficult operating system
to learn.
00:39 < sstangl> rsc9: I will look into porting Go to plan9 after I have
some more free time to become familiar with the language.
00:40 < kuroneko> opensourcenut: dunno about that - it's different - if you
go in thinkings it's unix, you just make it harder for yourself.
00:40 < sstangl> opensourcenut: there aren't enough resources available, and
most people in my experience are afraid to ask questions.
00:40 < kaib> joeyadams: negative, all the work has been on little endian
configurations.

friendly :)
00:40 < opensourcenut> sstangl: is it?
00:40 <+agl> vhold: certainly it's not happening at the byte level, I
suspect it's happening somewhere in there, but I would have check the sources to
be sure.
00:40 < sstangl> opensourcenut: yes, very.
00:40 < opensourcenut> sstangl: would you use plan9 on a server ?

00:40 < opensourcenut> *production, I mean
00:41 < kaib> joeyadams: at some point part of 5l was in big-endian but we
switched to little endian.
00:41 < sstangl> opensourcenut: I would not trust it to be secure enough to
run facing the world.
00:41 < sstangl> for internal things, it can be nice.
00:41 < opensourcenut> sstangl: but it has such interesting security
features
00:41 < opensourcenut> sstangl: the namespaces and such
00:41 < sstangl> opensourcenut: it's basically a special version of
Kerberos.
00:42 < joeyadams> I got this compiling go: --- FAIL: net.TestDialError

impossible.

00:54 < opensourcenut> agl: Go has the ability to use assembly?

01:43 < gcarrier> lol, that's strange!?
01:43 <+agl> gcarrier: if so, we would be interested to know why :)
01:43 < gcarrier> agl: let me have a look
01:43 < opensourcenut> what causes this?
01:43 <+rsc9> os x firewall assumes all dns requests go through the system
libraries, and ours don't
01:43 <+rsc9> we use udp directly which the firewall does not allow. maybe
it thinks we are some scary p2p app
01:44 < gcarrier> ok, the firewall does open a window to ask for permission
01:44 < gcarrier> but it closes extremely fast
01:44 <+agl> rsc9: there's probably a Mach-port to talk to the local DNS
cache.
01:44 < Go-Nuts> Yeah I saw that and was wondering what happened. was
typing at the time so thought that's what did it
01:44 <+robpike> i've seen that window flash. any idea how to deal with it?
01:44 <+rsc9> even if you grant permission i think it doesn't work. i don't
remember.
01:44 < gcarrier> i had time to allow one, not the other, and now one of the
2 tests run ok
01:45 < harryv> you rendered go! un-googleable :/
01:45 < kuroneko> there should probably be a thing up somewhere that says
that the tests assume internet connectivity.
01:45 <+rsc9> agl: i know, but i've been ducking the implementation of true
mach rpc

01:53 < opensourcenut> I've pulled like 5 times in the last hour haha
01:53 < gcarrier> rsc9: i don't think so. osx just waits for an answer to
bind the socket, so if you timeout and give up it's normal to stop asking for
permission
01:53 <+agl> opensourcenut: you issue has been fixed by a check in. You can
run `hg pull -u` to sync your tree to the tip of trunk.

01:54 < Eridius> err, agl, that page gives erroneous information. It says
to run `hg change` when you're ready to send a change out for review, but that
tells me hg: unknown command 'change'

bug at code.google.com/p/go
01:54 <+rsc9> Eridius: you did not enable the code review extension
01:54 < Jerub> well, basically, there's no way at all to implement a DNS
resolver that matches the rest of the system without loading and calling a library
because nsswitch.conf allows you to provide loadable shared object files as
resolver plugins, which is how mdns works.
01:54 <+ian1> Eridius: you need to add the codereview plugin to your .hgrc
01:54 <+agl> Eridius: you need to install the codereview extension.

01:55 * Eridius has zero familiarity with mercurial
01:55 <+agl> Jerub: yes, this is unfortunate. OS X and (even) Windows are
much better in this regard.
01:55 < Eridius> ahh, I see where it tells me to add that now
01:55 < joeyadams> Reminds me of what happened in #gsoc when people were
waiting for students accepted to be announced.
01:55 < Eridius> silly me, I clicked on the "Make a change" hyperlink at the
top
01:55 <+ian1> Eridius: that's good, because Go's code review plugin is
somewhat different from standard Mercurial
01:55 < Jerub> agl: dns on osx is also weird. there are two resolvers on
the system, and some tools use one, or the other.
01:55 <+agl> opensourcenut: wait, you might be right. You might have a

01:56 * Eridius installed go on two different 10.6.2 systems and had no net issues
01:56 < benno> anyone know if the current build system supports
cross-compiling for arm?
01:56 < brianmacdonald> In
http://golang.org/doc/effective_go.html#web_server line 16 template.HtmlFormatter
01:56 < brianmacdonald> should be template.HTMLFormatter and 33
template.HtmlEscape should be HTMLEscape. See http://golang.org/pkg/template/
01:56 < benno> it doesn't seem to, although it suggests that ARM is support?
01:56 < defectiv> anyone know off hand whot a recent core 2 duo is,
architecturally? 64-bit?
01:56 < opensourcenut> rsc9: okay what information do you need?
01:57 <+agl> Jerub: Linux distros should include a local DNS cache. I have
a NetworkManager patch for that, but it's very hard to get patches into NW.
01:57 <+agl> benno: yes, but some things don't work yet. (Like floats.)
01:57 < Jerub> agl: I'm not trying to say, "you're wrong" - far from it, DNS
resolution by software sucks in huge ways, and the libc resolver is indeed crap
(no way to do an async query for one)
01:57 < antarus> agl: we might have some staff to work on that later this
year
01:57 <+agl> defectiv: Core 2 is typically amd64
01:57 < benno> agl: I don't want floats on arm anyway :)

02:38 < witeness> soul9: you mean in the terminal?
02:38 < soul9> (it's the stuff behind the 4 that counts ;)
02:38 < mrd`> flea__: Have one goroutine manage the map, and have others
send messages and get responses from it.
02:38 <+agl> bobappleyard1: probably already fixed. hg pull -u

02:39 < flea__> ok, and so the processing goroutines have a channel to/from

02:39 < soul9> you wrote export PATH=$

02:42 <+rsc9> but if you are sharing something at the granularity of a map,
it's not required to use a channel. for small things sometimes a lock is just
what you want. channels are better for managing overall program structure than

05:01 <+iant> Jerub: it will be \xe1; a string is a sequence of bytes; a
string literal is encoded into UTF-8; you can use range over a string to get UTF-8
characters
05:01 < Jerub> i'm reading the documentation and I don't see this clearly
defined.
05:01 < NelsonLaQuet> That's odd. The only way that I could figure out how
to consume the first return value was to do this:
05:01 < NelsonLaQuet> bytes, errors := io.ReadFile(file);
05:01 < NelsonLaQuet> then write an empty "if errors != nil" statement to
supres the unreferenced variable error.
05:01 <+iant> antarus: that would be a library issue, we'd love to have help
with the libraries
05:01 <+iant> NelsonLaQuet: Use the blank identifier
05:02 <+iant> bytes, _ := io.ReadFile(file)
05:02 <+kaib> harryv: specifically, the android reference platform (and a
large number of the actual deployed arm cores) don't have hardware floating point
support.
05:02 <+iant> Jerub: which part is not well defined?

05:02 < NelsonLaQuet> is there any way to consume a single return value in
the same line? Like: functionCall(multiReturnFunction()[0]) ?
05:02 < shardz> Are there any vim syntax files for Go yet?
05:02 <+robpike> Effective Go covers a lot of this material.
http://golang.org/doc/effective_go.html
05:03 <+robpike> NelsonLaQuet: not smoothly.
05:03 < abbyz> should it not be valid to use [...] as the array size in a
function parameter list?
05:03 < NelsonLaQuet> I read the *very* short section on return values and
it didn't mention any way to do what I want.
05:03 < NelsonLaQuet> shardz: yeah, it's in the repo
05:03 <+iant> NelsonLaQuet: interesting idea, but no
05:03 < Jerub> iant: the unicode/utf-8/string definition. it's clear that
unicode string literals are in the language, but not that the data will be stored
and accessed as utf-8
05:03 <+iant> shardz: misc/vim/go.vim
05:03 <+robpike> arrays are statically sized. ... implies dynamic in that
context
05:03 < shardz> Excellent, thanks.
05:04 < Jerub> iant: I assume that if I have a byte sequence that contains
an invalid utf-8 sequence and I cast it as String, there aren't any possible
errors?
05:04 <+iant> a []byte will convert to exactly that sequence of bytes in a
string
05:04 < _Hicham_> for linux people, put ur environment variables in
/etc/profile.d
05:04 <+iant> they don't have to be valid UTF-8 in that case
05:04 < Jerub> okay, good.
05:04 <+iant> a []int sequence will convert to that sequence of characters,
encoded in UTF-8
05:04 < wcn> Jerub: it returns aninvalid token, but will let you iterate and
recover the rest of the data.
05:04 <+iant> I mean, string([]int)
05:05 < Jerub> wcn: not utf-8 doesn't mean invalid.

the scope of the programming language.
05:11 < bnijk_> there's no way that's true
05:11 < sanxiyn> Strings shall be immutable
05:11 <+iant> bnijk_: if you want a mutable string, use []byte

05:13 < bnijk_> or do you mean, explicit string copying on the part of the

05:13 < dw> hi there. is there a specific part of the language spec that
mentions introspection features? i can't find anything in the docs at all
05:13 < uriel> Jerub: it can be, but dynamic linking is no fun at all, it is
pain and missery all the way
05:13 <+iant> dw: see the docs for the reflect package
05:13 < Jerub> before go gets too big, are there any concrete plans for
package management or a software index?
05:13 < kuroneko> bnijk_: if strings are mutable, you need a distinct copy
reference vs copy contents. immutable strings are always copy reference, but
modifications must yield a new string.

05:39 < dj_ryan> otherwise you cannot write data-intensive database type
systems programming without suffering somewhat
05:39 <+iant> msw: ah, you have a sed which doesn't match centered-dot--that
seems quite likely
05:39 < dj_ryan> Erlang avoids this by having thousands of tiny heaps, each
process is GCed independetly
05:39 < uriel> harryv, iant: thanks, lets see how much code I can get
written once I wake up :) (just moved to a new flat, so Go is going to compete
with actually unpacking my stuff...)

05:40 < Capso> andguent: Limbo is not for modern UNIX; Limbo also requires
Dis

05:40 <+iant> msw: yes, maybe
05:40 < dj_ryan> except they call them 'references'
05:41 <+iant> justinvh: sorry, no syntax for that, have to write a loop or
call a function
05:41 < ajray> dj_ryan: i love watching the CS professors here try to
explain why references are not pointers and how java doesnt have pointers ('unlike
that ugly c')

05:42 < mrd`> Jerub: I think so; it's also process specific because each
process gets its own dedicated heap.
05:42 < NelsonLaQuet> I come from a C++ background - references are typesafe
and don't allow pointer arithmetic.
05:42 < dj_ryan> so are go's pointers pointers or references?

conversation willn ot end well ;)
05:42 < uriel> iant: I got it right though that because Go has no pointer
arithmetic, it could run without an mmu, like Limbo, right?
05:42 < kuroneko> and you can't diddle a reference. :)

05:43 < codedread_> so it was said that go links statically - is that by
default? is there a way to link a go program to libraries built in go?
05:43 < kuroneko> uriel: hey, we had pointer arithmetic before we had MMUs
05:43 < uriel> iant: because that is one of the coolest things about
Inferno, to be able to run reliably and fast on things like the Nintendo DS
05:43 <+iant> codedread_: 6g/8g link statically
05:43 < kuroneko> :P
05:43 < dj_ryan> once you remove arithmetic you cant create arbitrary
pointers, now you have 'references' in the style of java. Aka pointers that have
more working behind the scenes (ie: for compacting GCs)
05:43 <+iant> msw: same error?
05:43 < msw> iant: yea
05:43 < uriel> kuroneko: yes, but I mean safely running multiple programs

05:45 <+iant> NelsonLaQuet: the http library is more aimed at a standalone
server, running under CGI is simpler but I don't know that there is any direct
support for it
05:45 < NelsonLaQuet> nevermind, that's a stupid question... I guess my
question is that are there any nice wrappers for using go as a CGI module under
apache?
05:45 < kuroneko> and it's been done with half-an-MMU (80286 protected mode
lacked the virtual addressing modes, but did have page protection)

05:45 < codedread_> iant: ok, that was how i built my helloworld app, but
would it be possible to link dynamically to libraries built using go?
05:45 < mrd`> _Hicham_: I suspect the Go compiler just uses static linking
because it's simpler, and it's based on the Plan 9 toolchain, which I don't

05:50 < dj_ryan> here's another question, will go be domantly CSP for
multiprocessing? I'm not sure that fits all needs (imagine databases)
05:50 < NelsonLaQuet> I wrote a neat little web server thing that serves out
html templates in a folder; using the request path to locate them. Pretty
neat.... Though am now trying to figure out how I would implement a nice
web-centric MVC framework and OR/M over this. It's architecture is really
different then other languages...
05:51 < javarants2> there is an http server in the http library
05:51 < javarants2> i think it is the one that is serving their site
05:51 < DJCapelis> databases are not worth designing for I think... they
always mess things up and the hacks you have to put in to support them seem to be
rarely helpful to anything else.
05:51 < NelsonLaQuet> yeah, I cheated and used that. But I would prefer to
expose any application over fast CGI so that I can take advantage of apache's
other features and stability.
05:51 < antarus> dj_ryan: It may be that go is not a good language to write
certain kinds of applications in.
05:51 < mrd`> [absolutist argument with zero support]
05:52 < dj_ryan> antarus: uh, then wtf is it for?!
05:52 < no_mind> DJCapelis, but you still need databases.. they are
necessary evil in comp applications
05:52 < dj_ryan> if you cant write a database in a systems programming
language, what kind of systems programming language is it
05:52 < javarants2> i didn't see native support for C libraries, is that in
there somewhere?
05:52 <+iant> dj_ryan: go uses goroutines and channels, yes, it's the ideas
from CSP plus a bit more

writh in go.
05:52 < codedread_> i think i would really like to see dynamically linked go
programs (with the 'go' standard libraries available as shared object libraries)
05:52 < dj_ryan> so with CSP you just bottleneck for certain things
05:52 < DJCapelis> NelsonLaQuet: Use databases with go all you want.
05:52 < dj_ryan> eg: ETS tables in erlang are bottlenecks
05:52 < no_mind> DJCapelis, so we should drop go for db related apps ? that
means 90% of web apps
05:52 < mrd`> dj_ryan: Not true.

05:53 < DJCapelis> no, I just said the actual databases themselves.
05:53 < joeyadams> I guess go doesn't have DB packages yet?

05:53 -!- Robdgreat [i=rob@unaffiliated/robdgreat] has joined #go-nuts

05:53 < dj_ryan> DJCapelis: right, writing data storage systems in go might
be interesting, since your choices are mostly Java and some C++ (sorta)
05:53 < DJCapelis> no_mind: using a database maps nicely into goroutines.
05:53 < joeyadams> Does it have good reflection support for tasks like

05:54 < antarus> joeyadams: I suggest you check out the unsafe module
05:54 < NelsonLaQuet> I'm assuming that we can link go with C code, though,
right? With the gogcc compiler? In that case you could re-build the C libraries
for mysql and whatever, then build a nice OR/M over that.
05:54 < antarus> joeyadams: (which is where all the reflection is, afaik)
05:54 <+iant> Go is definitely not Erlang
05:54 < javarants2> iant: how would you compare goroutines to libdispatch +
blocks? i have been looking at that and it solves quite a few of the annoyances
in writing concurrent C code.
05:54 < DJCapelis> NelsonLaQuet: you can, it's unsafe though, generally...
05:55 < NelsonLaQuet> true
05:55 < no_mind> where do I find db packages for go ?
05:55 < joeyadams> Hmm, I wonder manually implementing a "work queue" is
typically necessary in go
05:55 < dj_ryan> there is this strong trend in the open world for large data
scale things to be written in Java (see: hadoop, et al)

05:55 < ajray> if i wanted to contribute the bash completion file to

non-existent. It is only used in terms like "compatibility" and "community".

make calls outside of your own internal ABI

cores dynamically, which some power management tools might want to do)

06:48 < chrome> ah hmm.
06:48 <+robpike> there is already runtime.GOMAXPROCS(int)
06:48 <+agl> scriptdevil: it's a little odd, but you can probably ignore it.
06:48 < joeyadams> I just ask because runtime.GOMAXPROCS(int) looks kinda
hackish (with the capital letters)
06:48 < scriptdevil> agl: :) Thanks
06:48 < antarus> It looks hackish because commented above it says "this
should go away when the scheduler is improved" :)
06:49 < joeyadams> and if the num cpus function doesn't need to go in
runtime because syscall exists, we'd have two similar-purpose functions in two
different modules
06:49 <+robpike> joeyadams: it's spelled like that because of the env var.
you're right it looks hackish.
06:49 < drusepth> I just read about Go on /. and am considering looking
into it tomorrow (it's a bit late tonight), but I'm curious whether it has

making it based on the repo would be fine, but you still have the env var issues

different types, no. see the language design faq

07:45 <+robpike> jdp: no plans. are they a problem other than the initial
setup? we crosscompile all the time and being able to flip builds is very handy
07:46 < jdp> no they aren't, you're right
07:46 < scriptdevil> sjbrown_: Can Google ever go wrong is the question. I
dont wanna sound like a fanboy. But I am positively amazed at the maturity and
completeness of a 2 day old language. (Forget the 2 years of development)
07:46 <+robpike> you need asn1 for x509 for SSL
07:46 < Eridius> robpike: I'm of the opinion that crosscompiling should be
achieved by passing -arch flags to the compiler
07:46 < Eridius> and with that, I'm going to sleep. g'night
07:46 < uman> when (if ever) will Go be available for Windows?
07:46 < KiNgMaR> <- wondering about Windows support as well
07:47 < mjard> heh
07:47 < epalm> windows isn't mentioned anywhere in the faq
07:47 <+robpike> Eridius: that means different makefiles and all that, or
else some other configuration management setup. env vars work great
07:47 < sjbrown_> scriptdevil, are you waiting for the Google Bob?
07:47 < mrd`> Pft, use a real OS. :P
07:47 < uman> also, my humble recommendation is that you put this in the FAQ
07:47 < uman> mrd`, that's a useless answer
07:47 < theatrus> oh I missed the whole ssl library, last I dealt with asn1
was with SNMP on embedded microcontrollers
07:47 <+robpike> uman: you're right
07:47 < mjard> uman: you have to respect the fact that it's very very rare
that the tables are turned this way
07:48 < eydaimon> Eridius: I'll email you the ticket

prediliction for unxstyl names
07:48 < eydaimon> Eridius: I'll file it as per usual
07:48 < antarus> Eridius: meh, I dunno when I cross-compile I typically set
CHOST, CTARGET, etc...and my build system handles talking to the compiler for me;
I don't see how this is conceptually different?

are advantageous mostly when *reading*
07:54 <+robpike> Morphius: have you done hg pull -u recently? some network
bugs were fixed tonight
07:54 < epalm> should go code be written with the number of available

10:46 < voxadam> I just watched Pike's Go presentation at Google on YouTube.
He mentioned that there was work underway (or maybe scheduled) to replace the
current mark-and-sweep GC with something more advanced. Specifically, he
mentioned The Recycler from IBM. IBM claims a maximum pause time of 2.6 ms. If
this is true what are the chances of Go being suitable for real-time/deterministic
programming?

things.

E.g. Ubuntu generic kernel peaks 50-100 ms latency spikes all the time, while
many other distributions (and Ubuntu rt kernel) can keep latencies under a few

11:41 < deafmetal> i have a rather noobie question...
11:42 < deafmetal> I'm getting an error when i try and run all.bash
11:42 < deafmetal> liek so: $GOROOT is not set correctly or not exported
11:42 < npe> deafmetal: did you add GOROOT to your bashrc and export it?
11:42 < deafmetal> GOBIN=/Users/deafmetal/bin
11:42 < deafmetal> GOARCH=386
11:42 < deafmetal> GOROOT=/Users/deafmetal/go
11:42 < deafmetal> GOOS=darwin
11:42 < deafmetal> yes.
11:43 < deafmetal> that's the result of my env } grep
11:43 < Element14> did you explictly export it?
11:43 < npe> bash -c 'echo $GOROOT'
11:43 < npe> see if you're successfully exporting it.
11:43 < deafmetal> ok
11:44 < deafmetal> deafmetal-2:~ deafmetal$ bash -c 'echo $GOROOT'
11:44 < npe> and nothing?
11:44 < deafmetal> no, it gives me the path
11:44 < madac> Put export in front of everything, e.g.:
11:44 < madac> export GOBIN=...
11:44 < alt^255> deafmetal: in the same terminal where you're running

once I understand it better. In this case I'm coming from a sysadmin role, not
really a programmer yet.
11:53 < blasdelf> it's more about trying the kind of toy problems that lend

11:56 < alt^255> what about plan9 and inferno, how they relate to Go?
11:56 < Innominate> leitz: Can't hurt to try, but an experimental language
is probably not the best place to start
11:57 < blasdelf> alt^255: written by the exact same authors, espousing many

11:57 < hnsr> anyone know what I might be doing wrong here?
http://pastie.org/693501 it fails to find quietgcc even though it is in my PATH,

11:57 < leitz> Innominate, I'm rather slow sometimes, so the language will
mature faster than my programming. :)

12:01 < blasdelf> madac: It has interfaces
12:02 < blasdelf> It seems that they've avoided GADTs, possibly because they
don't mesh with Protocol Buffers
12:02 < madac> blasdelf: Interfaces and generics are orthogonal concepts.
Yes, they both support polymorphism, but in very different ways.

14:56 < watermind> engla, temoto: is there any obvious reason why it's
inclusive on left and exclusive on right??
14:56 < Cool_Fire> 1. Is there (any plans) for a IDE for go?
14:56 < nc> _dr: i came across a new error though, much further down the
line of execution... so if you're gonna build on OpenBSD or a system that doesn't
use gmake by default, just make sure you change 'make' to 'gmake' in *make*.bash
14:57 < temoto> watermind: i actually find it useful in some cases. I need
to provide good example, but i don't have one in mind right now.
14:57 < Cool_Fire> 2. What about GUIs?
14:57 < engla> watermind: there are two good reasons. 3-1 = 2, so we should
make the interval halfopen. and -1:2 to include 0,1,2 would suck so 0:3 for 0,1,2
is better
14:57 < scriptdevil> Cool_Fire: It has good support for vi, emacs, xcode
14:57 < Cool_Fire> ok
14:57 < _dr> ok thanks nc, alias make=gmake should do
14:57 < engla> watermind: you should ask dijkstra about this

interval of indices. ewd suggests that experiment shows that other conventions
than [,) are confusing. I think that [a,b) with len = b -a is very logical.

obvious that the cost is proportional to the length of the slice.

16:12 < mmu_man> $BASH stuff shouldn't actually be needed, but it wouldn't

16:13 <+agl> me__: well, we don't link again libc so using pthreads wasn't
an option

16:21 < Associat0r> iant also the lack of operator overloading or at least
defining bothers me

just an alternative
16:21 < me__> hmm, when using limbo, i found i wanted weak refs; have there
been any thoughts towards that?
16:21 < monov> iant: ok
16:21 <+iant> Associat0r: the language is not fixed in stone but I doubt Go
will ever get operator overloading
16:22 <+iant> me__: I have not heard any discussion of weak refs
16:22 < Associat0r> iant the thing is I do a lot of numerical stuff and
having to have method names for math operetors is not so nice
16:22 <+iant> Associat0r: understood; language design is always a tradeoff

16:22 < mpowers> I'm curious about how Go achieves such awesome compile
times relative to C/C++. Is there a quick answer for this, or a writeup of the
techniques used to improve compile speed?
16:22 < Wezz6400> Being a fan of C++ I don't mind Go being different, C++
already exists so to create something very similar would be pointless imo
16:23 <+iant> mpowers: the main reasons are the simple syntax and the
package system
16:23 < ag90> I'm curious. Go has some amount of C interoperability. Am I
right?
16:23 -!- blackmagik [n=blackmag@unaffiliated/blackmagik] has joined #go-nuts
16:23 <+iant> ag90: limited but yes, see misc/cgo for an example; it's not

16:23 < Associat0r> iant that I understand, OCaml also made that tradeoff
16:23 <+aclements> me__: Russ and I did discuss weak refs a while back. I
believe the conclusions was that Go needs something like weak refs.
16:23 < pbunbun> iant: So you're saying it's the language itself being easy
to compile, not just the compiler being good?
16:23 <+iant> pbunbun: the compiler is good, but, yes, the language is the
key
16:23 < thotypous> does anyone have an example using closures please?
16:24 < Associat0r> Wezz6400 well I don't want Go to be similair to C++, but
at least do what C++ can do
16:24 < mpowers> so there is no preprocess step in Go, i guess?
16:24 <+iant> thotypous: there are some examples in the course slides, I
think on day 2
16:24 < pbunbun> iant: So the gcc-based compiler is (or should/could be) far

16:24 < pbunbun> Ok cool, (haven't actually downloaded it yet, when I get

16:25 < albertito> iant: thanks!
16:25 <+iant> Associat0r: gccgo does it, I don't know offhand whether 6g/8g
do it

16:27 < mpowers> out of curiosity, besides preprocessing, what are the
language features of say, C, which cause the most amount of "work" for the
compiler, and how does Go fix that? Do these improvements come "free", or is
there a cost paid in complexity/readability of code?
16:27 < Associat0r> Wezz6400 well it's not just C++ that does op overloading
also asking about GC is a valid question since it's a systems language
16:28 < ment> mmu_man: hmm s/waidpid/waitpid/ maybe?

slower than reading in compiled package information

parse, notably the declaration syntax

18:21 < three-f-jeff> kaib: one of my first thoughts when reading the docs
on golang.org was "how would this work for implementing a kernel", and you would
want to do the entire thing in go, but you'd have to customize the gc to work at
the kernel level (eg, being mindful of page tables and segments)

18:33 < NfNitLoop> bear: Oh, huh. trying the pull now.
18:33 * techknowlust checks zsh command history
18:33 < techknowlust> one sec
18:33 < techknowlust> bear: hg clone
18:33 < musty> jvogel_, *shrug*
18:33 < musty> hg clone -r ?
18:33 < swamytk> the compilation of go took around 2 to 3 mins in AMD Quad
core machine with 4GB RAM on ubuntu 9.10
18:33 < bear> techknowlust, yea, try: hg pull -u now and see if you get some
new updates
18:33 < techknowlust> I'm not familiar with mercurial, could this be the
cause of my problem?
18:33 < techknowlust> ok
18:33 < PHG> after you pull, you have to update
18:33 < PHG> iirc?
18:33 < NfNitLoop> techknowlust / bear: ah, yep, I see changes.
18:34 < musty> that's what -u does
18:34 < musty> iirc
18:34 < PHG> i'm sorry
18:34 < NfNitLoop> seems strange to have to pull immediately after cloning.
18:34 < NfNitLoop> (coming from bzr) :p
18:34 < temoto> Hey, BTW, shouldn't ./all.bash run some make with some -jN?

right now
18:34 < musty> jvogel_, your wish has been answered.
18:34 < techknowlust> bear: if I clone would the .hg directory be included ?
18:34 < JakeSays> so no go for windows? :(
18:34 < musty> Did anyone have qualms when installing with bash?
18:34 < emet> this web server code example is pretty cool
18:34 < temoto> I see MAKEFLAGS=-j4 in make.bash. Great.
18:34 < jvogel_> musty: hehe
18:35 < emet> no I got it to compile and install
18:35 < bear> techknowlust, after running hg clone you should see a .hg dir
as part of the new files - yes
18:35 < emet> it was necessarily hard IMO, maybe use autotools next time?
:o
18:35 < PHG> i have a question though, why so many gotos in the source?
18:35 < PHG> though i havent looked through much.
18:35 < weggpod> how to convert string in int when is it possible
18:35 < weggpod> ?
18:35 < musty> jvogel_, Going to /QUERY him now? :)

required argument to the hg pull command

18:36 < olegfink> silly question: I'm trying to call an anonymous func from
itself. The first idea was to just generate an OCALL with curfn->nname, but of
course anonymous funcs don't have ->nname. Is the only possible way to do this
is to add OCALLSELF in addition to OCALLFUNC and implement that in the backend?
18:36 < pancake> musty: yeah sorry im just busy at work
18:36 < bear> emet - it's a bootstrap compiler environment that is in flux -
i'm sure once they get the crosscompiler set for each environment i'm sure the

18:57 < charles_> iant, I know tradition and all, just a little easier than

18:57 < temoto> compared to nonexisting python optimizer
18:57 < bobappleyard1> emet: yeah, pretty much. an object implements an
interface if it has the required methods

18:57 -!- mode/#go-nuts [+v agl] by ChanServ
18:57 < emet> but the object doesn't need to even know about the interface
right?
18:57 < tetha> temoto: you do know that there are optimizing python
implementations around?
18:57 < bobappleyard1> emet: no it doesn't
18:57 < fynn> temoto: ... that's comparing apples to oranges.
18:57 < emet> that's awesome
18:58 < grawity> I just tried building Go on a Debian 5 VPS, and all the
final tests fail with "cat: /tmp/gotest1-1247-grawity: No such file or directory"
(http://phoenix.binaryhex.com/~grawity/all.bash.log)
18:58 < emet> that is really cool
18:58 < temoto> emet: no objects. The best implementation of object model.
18:58 < engla> temoto: google is working on optimizing python ;-) among
others
18:58 < charles_> inat, BTW very good job so far, it is at the right place a
the right time, (25 year C programmer here). ;)
18:58 < temoto> tetha: do you mean unladen?
18:58 < saml> can i build using mingw?
18:58 < emet> unladen swallow
18:58 < olegfink> iant, I was trying to call an anonymous func from itself.
The mst obvious (and wrong) idea was to generate an OCALL with curfn->nname,
and the only other option I see is to add OCALLSELF in addition to OCALLFUNC and
implement that in backend, but that look awful. Do I miss anything else?
18:58 <+iant> grawity: I don't see that in yoiur log
18:58 < three-f-jeff> emet, temoto: the 'no objects' OO is what blew my mind
when I read the specs.
18:58 < tetha> temoto: unladen, pypy, jython, ironpython, w/e

there's no bin ...
18:59 < e2d2> musty, i had that when i didn't have $GOBIN in path

users...
19:02 <+iant> well, we're not distro maintainers

19:04 < bobappleyard1> travisbrady: members?
19:04 < phoodle> three-f-jeff: no, i'll add it
19:04 <+iant> You need to do for p := range f.Iter() { e := p.(string);
19:04 < bear> charles_, the issue of app installs is moot with a single
binary generated by the compiler - you just have to ensure you have binaries for
all target platforms
19:04 < eno> iant: besides pkg and GOBIN/*, what need to be in distribution
for a golang package?
19:04 < bear> charles_, but if the language starts generating traction and
libraries become common, then package management becomes an issue and that's a
whole other pain in the tuckus

19:05 < delza> phoodle: I had the same problem. You $GOBIN has to be in
your path, has to exist, and it can't be in your path as "~/bin" but works as
"$HOME/bin"
19:05 < bear> charles_, not yet as the compiler generates very specific
instructions - you could try the gccgo frontend but even that would generate
specific arch targeted binaries
19:05 < ment> iant: works, thanks
19:05 < phoodle> three-f-jeff: thanks, adding to path seems to work, is now
compiling, delza: thanks as well
19:05 < charles_> bear, I only mention it because it is hard, if it was
easy, I'de have the solution
19:05 < travisbrady> bobappleyard1: the number of people in this channel
19:05 <+iant> eno: I think that's it
19:06 < ajray> is there a Go book yet?
19:06 < bobappleyard1> travisbrady: oooh i see
19:06 < Selar> geez
19:06 < charles_> bear, need to think ahead if possible
19:06 < bear> charles_, hehe - true - but I think the golang guys are
working on the "crawl" phase before they can get to the "sprint" phase that is
what distro packages are (IMO)
19:06 < Selar> it just came out
19:06 < Selar> the tutorials and videos are awesome right now
19:06 < KillerX> why can I not do this: http://pastebin.com/m5d74a6df (using
a struct type as values in a map)?
19:06 < bear> charles_, yea, the issue will become important as soon as they
allow for linking to outside libraries
19:06 < charles_> bear, the key to a system is design and getting that
right, MUCH hard to re-design than the other way around

20:04 < ajhager> agl: I've seen this possible in Python's ctypes, but I've

20:04 < temoto> Yeah, i'd like to see 1_000_000 too.
20:04 < KirkMcDonald> So 1_000_000 is a valid literal in D.
20:04 < Dreamr_3> so is there a textmate syntax? :)
20:05 < glewis> In D, you can also use $ with an expression, like buf[1:$-1]
20:05 <+agl> ajhager: what you can't do is pass a pointer to a Go function
into C. I don't know the specifics of the GL libs however.

think go does it better.
20:16 < ajray> also, i'd like to add my voice to the templating question.

20:16 < diabolix> I think if you need a complex feature, the language should
provide a means to add it, not depend on it.

20:17 < kmc_> with nulls, unless you have some way to structure computation
(e.g. monads), you end up writing "if (x == NULL) return NULL" every other line
20:17 < diabolix> like, why can't the 'go' keyword be a function that takes
a closure as an argument?
20:17 < ajray> diabolix: would templating qualify as a complex feature?

20:22 < aaront> check the permissions on bin
20:23 < Dreamr_3> string#Join
20:23 < ajray> Dreamr_3: strings are immutable, byte arrays are not.
20:23 < danderson> diabolix: goroutines, due to their form, need support
from the runtime to be able to multiplex several goroutines on a single thread.
So from that point, they must be in the runtime. As for why the syntax is a
keyword rather than a function, I don't know and defer to the creators of the
language for widsom.

22:26 <+iant> I do not have any idea, we aren't working on one ourselves
22:26 < timmcd> iant: How many people are currently working on the Go
source, improving the language? (as we speak, that is.)
22:26 < KirkMcDonald> I am still not sure what to think of the fact that a
package implies nothing about the source files which comprise that package.
22:26 <+iant> the team at Google is five or seven people, depending on how

22:27 <+iant> keithcascio: yes, all files in a package must be passed to 6g

specific niches, and that it's clear Go has application beyond those niches.
22:30 < hhg> fynn: Go should also be useful for writing massively scalable

22:33 < hhg> fynn: you would write goroutines that block on i/o, like a unix
process dealing with a single client, and you can use all the structured
constructs (loops, etc.) and it just blocks when it needs to and the state is on
its stack. you don't get into the awkward model where you have inversed all the
control with a "reactor" like event structure, where things subscribe to be called
22:33 < keithcascio> +iant, +robpike: all of java's most important packages

copy/pasting the body of the embedded object into the embeddee
22:58 <+iant> that is, given []SantasHelper, where SantasHelper is an
interface, you can assign a Reindeer to an element of that slice

the embedded object too

runtime.Goexit(); then you don't have to pass errors up a chain

the idiom to let one goroutine be owner of the map and then take requests on it

multiple changes in one tree
01:24 <+iant> ajray: otherwise, yes, different checkouts or different
branches or whatever seems best
01:24 < ajray> is that how i keep the different files separate then (remove
lines from submission file)?

for them
01:33 < ajbouh> i have some simple ideas, half-baked ideas on the subject -
is this the right forum for that?
01:33 < ajray> is there any code-diving tools for go? (like go-scope
instead of cscope?)
01:33 <+iant> droid0011: right, it's not in libc-dev, it's in linux-libc-dev
01:33 <+agl> droid0011: I don't believe that files in /usr/src are in the
search path for includes.
01:33 <+iant> which is a different package
01:33 <+iant> agl: droid0011 is trying to build gccgo
01:33 <+agl> iant: ok, I'll let you handle it then :)
01:34 <+iant> ajbouh: the mailing list may be more useful, unless they are

01:36 <+iant> ank3but_: at the moment, I think so, but as other people learn
the system and show good work we plan to add them
01:36 < ajbouh> iant: any reason you guys haven't gone with something like
"go func () { .. }, chan os.Error"
01:36 <+iant> like other open source projects
01:37 < ank3but_> iant: Okay...
01:37 <+iant> ajbouh: we've considered that and it may happen at some point,
but no promises
01:37 < ank3but_> go is interesting.
01:37 < ajbouh> iant: and you're suggesting that building something like
that would involve a lot of runtime hacking?
01:38 < ank3but_> i search for a while an other language but C was the best
for me.
01:38 < ank3but_> go looks cool
01:38 -!- Ruonkrak [n=john@74-140-218-7.dhcp.insightbb.com] has joined #go-nuts
01:38 <+iant> ajbouh: I don't think it would take that much hacking, it's
more a question of whether we think it is a good fit for the language
01:38 <+iant> we're trying to be very careful not to add unnecessary
features
01:38 <+robpike> ajbouh: the idea of getting a channel from a go f()
invocation makes sense. i've thought about it a lot, though, and worry that it
may be more complicated to do than it's worth. but we are still talking about it

for error handling - it turned out much simpler + robust than we expected
01:42 < nutate> Eridius: I just want to see if I can make sense of this from
the multicore standpoint... I know enough to be dangerous with pthreads, openmp,
cuda, etc...

01:42 <+robpike> ajbouh: is it written up?
01:42 < engla> since it would be hard to implement map(func, array)
correctly in the type system, what about list comprehensions ala Python; can
syntax support solve this;perhaps: a := [f(x) for _, x := range otherarray]
01:43 < kfx> droid0011: check libc6-dev
01:43 <+iant> engla: we do have range

01:43 < SRabbelier> is it possible in one line?

01:43 < rando> iant: ah, OK. that makes sense. I do like the direction of
this language. I think rob hit it on the head, programming became 'not fun'
unless you used a dynamically typed language. I'll be watching. As soon as I
think it's solid enough I'll try to use it in my production environment.
01:44 < SRabbelier> robpike: what's the goey way to do it?
01:44 < KirkMcDonald> robpike: So the elements of this dynamic struct have a
static type of reflect.Value. If I wanted to pull a static S out, I would say:
(*S)(unsafe.Pointer(field.Addr()))

01:44 <+iant> SRabbelier: I'm not sure just what you are trying to do,
actually
01:44 < KirkMcDonald> robpike: (After confirming that the type is, indeed,
that.)
01:44 <+robpike> SRabbelier: does foo() return a pair?
01:44 < rando> Eridius: I looked at it.... my head hurt.
01:44 < SRabbelier> robpike: yes, the usual 'value, err' pair
01:44 < Eridius> rando: hehehe
01:44 < SRabbelier> I'm implementing fibonaci to practice
01:45 < KirkMcDonald> robpike: Since unsafe.StructValue doesn't have a Get
method.
01:45 <+robpike> KirkMcDonald: you do not need package unsafe. you should
almost never need it.
01:45 < danopia`> rando, lisp is fun
01:45 < SRabbelier> and I see no elegant way to do the fib(n-2) + fib(n-1)
01:45 < KirkMcDonald> robpike: Er. reflect.StructValue, I mean.
01:45 < SRabbelier> (with fib returning value,err)
01:45 <+robpike> KirkMcDonald: reflect.StructValue has a Field(int) method
and NumField()

when you are caught fooling around
01:48 < droid0011> kfx: yes sure, it is in

02:03 < JBeshir> foo[0:len(foo)] seems... long.

02:04 < JBeshir> KirkMcDonald: So I can add it to an array.
02:04 < danopia`> gointrigue, did you use double quotes
02:04 <+robpike> JBeshir: if foo is an array and you want to promote it to a

02:05 <+robpike> KirkMcDonald: which is weird?
02:05 < Eridius> the biggest issue with making a git mirror is you can't
participate in the code review process
02:05 < SRabbelier> danopia`: I'm pretty sure that the github guys are
working on that regardless using hg-git
02:05 < KirkMcDonald> robpike: That &array gives a slice over the array.
02:05 < JBeshir> "cannot use &main_parameters[i] (type *string) as type
[]string" <-- Doesn't seem to work?
02:05 < KirkMcDonald> robpike: Maybe I am too used to C.
02:05 <+robpike> KirkMcDonald: actually it makes a lot of sense. a slice is
a reference to an array. &array doesn't become a slice, but it can be assigned to
one

03:06 < Ycros> Rob_Russell: ReadString only exists on bufio.Reader, not on
io.Reader, and it takes a delimiter to stop on - I just want to read the whole
thing into a string
03:06 < dgnorton> chrome: also had to "hg pull -u" before ./all.bash would
run clean
03:07 < ajbentley> anyway, i got it to build as far as it did by specifying
bash and gnu make instead of the defaults, but it dies building gopack
03:07 < Ruonkrak> was pleasantly surprised that ./all.bash ran clean (second
time) on Ubuntu after all prereqs were installed (386)
03:07 < Ycros> Rob_Russell: I mean, it works, if I pass in null as a
delimiter byte, and work on err == EOF. But I have to create a buffered reader in
between as well. It feels too verbose, and like there should be a simpler way of
doing it
03:07 < bobappleyard1> Ycros: io.ReadAll ??

There is struct B having an anonymous field A. stuct A has two methods attached:
A1, and A2. all that A1 does is call A2. B overrides the method A2. if i call
binstance.A2 then i get B.A2. If i call binstance.A1 then i get A.A2. is there a
way that i could get B.A2 in both cases?
04:38 < kmc> so is the conversion from my-concrete-type to interface{} and

04:42 < Ycros> gointrigue: yeah, it seems like there are issues with gccgo -
do you need gccgo as opposed to the default compiler?
04:42 < kmc> NfNitLoop, aren't interface methods basically virtual?
04:42 < NfNitLoop> and in fact, all those methods still seem to operate on a
struct that is the "superclass" equivalent.
04:42 < gointrigue> No, I was merely curious about using itt.
04:42 < ablegreen> what do you guys think of the language so far? I am
looking at the sample code and it doesn't seem to be simpler than C

04:42 < NfNitLoop> kmc: In a way, but not like virtual methods in C++ or
Java.
04:42 < pandrew> NfNitLoop: the way i see it each method is both virtual and
static. depending on how you call it. if you call it trough an interface it is
virtual. What i'd like to see is the ability to have a method with an interface
receiver, or something like that.

Library to be used with Go? ie, Ncurses?
05:09 <+iant> timmcd: do you mean to rewrite it in Go? Or do you mean to
call the C/C++ library directly from Go?
05:09 < kuroneko> libgo is good so far
05:09 < KirkMcDonald> Hmm. Not certain how to narrow down this segfault.
05:09 < chrome> timmcd: see misc/gmp

05:31 <+iant> easiest is make([]byte, 24)
05:31 <+iant> or you can do "var buf [24]byte" and pass "&buf" to Read
05:31 < Jerub> my brain parses [24]byte as a pattern matching 2byte and

05:32 < xor> Hi there.
05:32 <+iant> ArekZB: not really; taking the address of thing will make the

05:33 < ajray> is anyone working on git tools for go?
05:33 < dsal> iant: passing &buf doesn't compile. Nor does make: cannot use
make([]uint8, 24) (type []uint8) as type *[24]uint8 :/
05:33 < xor> Where can I find tools to help develop with go? I mean, is
there an Eclipse plugin, emacs plugin, something?
05:33 < ajray> xor: check the misc dir

05:33 <+iant> dsal: read doesn't take *[24]uint8, it takes []uint8, doesn't
it?
05:33 < dsal> Correct.
05:34 < xor> ajray: Thanks, will do.
05:34 <+iant> dsal: so where does *[24]uint8 come from in the above
05:34 < ajray> xor: i thats vim/emacs
05:34 < dsal> var hdrBytes *[24]byte = make([]byte, 24);
05:34 < ajray> i dont know about eclipse, but i'd love an eclipse plugin
05:34 < chrome> dsal: you can just do hdrBytes := make ([]byte, 24);
05:34 <+iant> dsal: ah, no, it has to var hdrBytes []byte = make([]byte, 24)
05:34 < ajray> xor: i'm also playing with the idea of making a cscope-like
goscope for code-diving in go
05:35 <+iant> or just hdrBytes := make([]byte, 24)
05:35 < ArekZB> xor: i don't think there is an eclipse plugin yet . as far

05:35 < Rob_Russell> weird that for a:=0, b:=10 ; a < b ; a++ {} is

05:58 < kmc> object casting is the best part of java?
05:59 < Jerub> kmc: uh, the lack of object casting brought in by generics
and auto-boxing i think he means.
05:59 < chrome> from what I can see, go doesn't *need* generics; it does
essentially the same thing with interfaces, but without the clumsy syntax.
05:59 < itrekkie> hi everyone, can someone clue me in on the -I flag for
6g? I'm trying to use a makefile to build .6 files (objects?) in a directory
sitting next to a src directory, but I cannot fix this "cannot find import"
problem. Are there some docs I'm missing; does anyone have a Makefile or similar
solution they'd be willing to share?
06:00 <+robpike> chrome: not quite. the unboxing is annoying and it's not
trivial to create a type-safe container. there are subtler advantages of generics
too. but they are tricky to get right
06:00 < KirkMcDonald> itrekkie: .6 files are both object files and header
files.
06:00 < tetha> chrome: I'd argue that no one needs that akward hack generics
are ;)
06:00 < KirkMcDonald> itrekkie: You use -I to point the compiler at the .6
files required by the package you are compiling.
06:01 -!- Speciak [n=kevinbum@c-98-213-173-184.hsd1.il.comcast.net] has joined
#go-nuts
06:01 < kmc> chrome, with generics you could write "map" without the
unnecessary runtime cast
06:01 < KirkMcDonald> itrekkie: Or, rather, to point the compiler at the
directories in which the .6 files are contained.
06:01 < Speciak> anyone want to give a beginner a quick run down on the go
language?
06:01 < wcn> robpike: as an implementer, what are some of the tricky
aspects?
06:01 < gointrigue> that command is borked
06:01 < itrekkie> KirkMcDonald: and the syntax for the flag is -I dir/,
-Idir/ or does it matter?
06:01 < ment> Speciak: http://golang.org/doc/go_tutorial.html
06:01 < chrome> kmc: coming from C that cast doesn't seem burdensome to me
06:02 < gointrigue> but it compiles now...
06:02 < KirkMcDonald> itrekkie: Both should work.
06:02 <+robpike> itrekkie: there's a subtle issue. if you don't install the
.a file into the pkg directory, like the makefiles in the existing pkg dirs, then
you probably want to write your imports as ' import "./file" ' so it finds them in
the current directory
06:02 < KirkMcDonald> itrekkie: But it must go first, before any of the .go
files.
06:02 < Speciak> I read the tutorial... is there any way to program in go
on windows?
